Introducing the B5 Systems collapsible precision stock (CPS) in medium size. Evolving from the esteemed cheek profile of the B5 SOPMOD and Bravo stocks, the precision stock integrates an adjustable cheekpiece and buttpad, perfectly fitting Mil-Spec carbine receiver extensions. Key features include internal tensioners for stability, ambidextrous fixed and quick-disconnect sling mounts and a gross length of pull adjustment with a lockout mechanism. It also boasts an underside M-LOK accessory mount and color-matched hardware for a cohesive look. The CPS medium is designed to fully collapse, clearing the M4 charging handle effortlessly.
